Mechanical and Deformation Behaviors of Wyoming Shales


Abstract This paper presents a laboratory investigation to understand the mechanical and deformation behaviors of Wyoming shales. Seven shale samples were collected from different locations in Wyoming, including different formations, geologic ages, and depths. Thirty-three specimens from seven samples were prepared for a series of uniaxial and triaxial compression tests. In addition, porosity and specific gravity tests were conducted on these cylindrical specimens. Using historical and recently completed test data, regression analyses were performed to establish prediction equations to relate uniaxial compressive strength (UCS), peak compressive strength Young's modulus (E), and shear strength parameters to physical properties. Some of the conclusions are: (1) UCS decreases with the increase in moisture content and porosity, (2) E increases with the decrease in moisture content and porosity, and (3) cohesion decreases with the increase in porosity. These recommendations are developed to facilitate the design and construction of transportation infrastructure in Wyoming.
